To play devil's advocate; how would you have had them handle the New Year's Eve situation better?
They were more worried about being associated with the accident than the accident itself. Lots of weasel words and excuses in trying to claim that the driver didn't work for them, or that the driver wasn't active or doing a trip.
If I worked for Uber, I would have posted something simple and left it at that e.g.
"We have been informed by law enforcement that there has been a traffic accident in San Francisco involving an Uber driver. We send our deepest condolences to the family and victims of this tragic accident."
The end.
Of course they care more about being associated with this particular incident than about the singular victim.
Are you going to call them out for not expressing condolences for the other hundred people that died to cars that day?
To my reading, it sounds like they simply had no way of knowing that the driver worked for them without the police giving them details on the driver.
